A dis the inner side ofthe end wall 16d coaxial ther with and the smaller end of aninner-casing "surrounds said peripheral flange and is secured thereto tobe supported thereby. Casing 40 is prises an outer casing 16a shown asof elongated A plug 29 (see Fig. 5). is threaded into the valve 23 andpipe 22 to the nozzle 21.

when not in use. As shown in *Figs. 1 and 4-, the lower block 32contains a.

like. platej39 having a peripheral flang is secur ed to also in theshapeof a frustuin of a cone and has an open large end disposed somewhatadjacent end wall 16%;, the inner end of nozzle 21 being locatedsubstantially at the end of casing 40. Casings 16a and to have openings15c and 40a at one side, extending lengthwise thereof, these openingsbeing alined in the two casings and said openings are spanned by aplurality of members 41 extending tn reac The members 41 are in theshape or'tlie segment of the frustum of a cone and the same have aslightly inturned flange 41a at their larger ends. Members 41 have theirsmaller ends directed towards the smaller-end of easing 16a and at theirends ongage and are connected to plates 43 which are parallel to thediametral plane extending centraily of the openings in casings 16a and40.

The plates 43 have one sideeistending along the outer side of casing 40and secured thereto and their outer edge is bent at an angle andembraced by-the folded end 16f of easing 16a extending alon the side ofopening 156. A plate 40?) eaten s across opening 16c at the larger endtheir of: andbetw'een casings 16a and 40. The member lat thoflarger endof the opening engages this plate lob. Casing 18a has a plurality ofopenings 16; in its lower side, these openings being in form ofelongated slots with semicircul ar ends.

mercoid control'ineinber 44 has connected thereto. {a tube or casing 45secured in and pass-- ingthrougl 'a plug 46 in the end of the radiatoroppositev plug 29, said tube 45 extending some distaniee into theradiator and containing a thern'iostatie element. Tnernercoid control 44is'provided for regulating the solenoid valve 23 and will be'suitablyconnected thereto.

In operation, radiator 10 will be as usual provided with a heatingmedium and as stated, tube 30' will'be connected to a source of waterunder pressure. The members 44 and 22- will be arranged so that upon theattainment of a certain temperature in the radiator, control member ll'will act to open the solenoid valve 23. The water from tube 30 will beheated in coil or tube 28 so as tobe more readily evaporated .andw'illpass through strainer-25 so as to be cleared ofall solid matter. Whensaid ature has'been attained, water can pass temperthrough Liquid isprojected by nozzle 21 lengthwise of casings 16a and 40 in the form of avery fine mist. Air rising, from radiator 10 passes into casing 16athrough the openings 16g and thence to the open end of casing 40 andinto said casing. The movement of theair into casing 40 will be inducedand assisted by the spray from the nozzle 21. The warm air passing intocasing 40 mixes with the finely divided liquid or mist sprayed thereintoand'a good portion of this liquid will be evaporated and pass with theair out between .the' plates 41. "Someof the liquid projected in sidethereof, at its smaller end, whichblocks are the fornrof mist willengage the conical surface of the'pl'atesal and as unit 16 includingthese the air and inlet is thus obtained and the air passing out ofcasings 40 and 1664 between plates 41 carries the desired amount ofevaporated liquid. Any liquid not evaporated and carried out with theair will collect on the bottom of casing 40 at the inner sidethereof andwill orain to the large end of easing a0 and drop into the large end ofcasing 16a as illustrated in Fig. 4. Any such liquid collecting in thelarger end of easing 16a will pass out through the nipple 34 into thedrain pipe 36 and will be carried away to a suitable drain. Thehumidified air passing out of easing 16a or unit 16 will pass throughthe grid 14g and through opening 14 in casing 14. to the rooms to behumidified.

In Figs. 6 and '7 the unit 16 is shown as applied to a radiator of thewell known copper plate type. In these figures a casing is shown similarto the casing 14, the same being mounted upon the legs 49. A radiator 51is provided which is of the type comprising headers 51a between whichextend the tubes 51b. The tubes 51?) carry a multiplicity of thin plates52 of copper or other metal of high conductivity. The plates 52 areshown as being enclosed at the sides in thin metal casings 53. Couplingplugs 54 are threaded into projecting hubs on the headers 51a and theinlet pipe 55 is connected with one of these plugs, the same havingconnected thereto the shut-off valve 56. The outlet pipe 57 connectswith the other plug 54, the same having inserted therein the trap 58.Supplemental end walls or partitions 59 extend from the topof casing 56downwardly parallel therewith, said partitions terminating at the top ofheaders 51b and having flanges resting on said headers. The front ofcasing 50 has an opening 50a therethrough adjacent its top and thisopening preferably has a grid 59b therein. The side walls of casing 50extend down in line with the top of legs 49 so that an opening isprovided at the bottom of the casing through which air may enter. Ahumidifying unit 16 shown in Fig. l-is disposed in the chamber in casing50 within the. walls 59 and it will be noted that it is disposed withthe members 41 and the openings 16c and 40a at the top instead of at theside as in Fig. 1. Rods 60 extend across casing 50, being secured to thesidewalls thereof in any suitable manner and these rods are embraced bythe hooks 20 and 19. A liquid supply pipe 61 is provided connecting withan L-coupling 62 threaded into a plug 63. There is one of the plugs 63threaded into the outer side of each of the headers 51a; A pipe extendsbetween the plug 63 and through one of the radiator pipes 51b. The otherplug 63 is connected by-pipe connections 65 to a strainer member 66, aright and left coupling 6'7 being inserted in the pipe 65. Strainer 66is connected by the pipe connections 68 to a solenoid valve 69 which isin turn connected by a pipe '19 to the nozzle 21 of unit 16. An elbowv'71 is disposed beneath a drain nipple 34 and a drain pipe '72 leadsfrom the nippie 71 to a suitable drain.

In operation heat will be supplied to the radiator 51- and the air incasing 59 particularly within partitions 59 will be heated. The unit 16will be brought substantially to the temperature in this chamber. Thesolenoid valve 69 will preferably be controlled by a humidistat in the-.rooms to be humidified. When the humidity falls to a certain point,valve 69 will be opened and when the humidity rises to a certain point,said valve will be closed. Said valve will, of course, be connected tothe humidistat by suitable electrical conductors. Said valve could alsobe connected to a thermostat in the rooms to be humidified so that itwould not open unless the temperature in the rooms was at a certainpoint. Assuming that valve 69 is open, water will be sup- :plied throughtube 61 and will be heated in the radiator 51. This water willpassthrough pipe "through the spaces between members 41.

69 tostrainer 66 and through valve 69 and pipe.

'70 to the nozzle 21. The liquid will be projected lengthwise of casings16a and 40 as already described and the air rising through the openings16g in the bottom of the unit 16 and will pass into the open end ofcasing 40. The air will commingle with the mist projected into said casing and a good portion of the liquid so projected will be evaporated andcarried with the air out This air will pass out through the grid 5% intothe room. As above set forth, any moisture which might strike or collecton the surfaces of members il will be evaporated and will pass out withtheair. Should any moisture collect in casing 19, it will drain to thelarger end thereof and into casing 16a and will pass out through drainnippic 34 into member '71 and through drain pipe 72. The water suppliedto nozzle 21 will be heated in passing through radiator 51 so that itwill be the more easily evaporated.

From the above description it is seen that applicant has provided ahumidifying structure which can be easily and efliciently used incombination with a radiator or other heating unit. The humidifying unitis simple and compact and yet functions to supply a'large amount ofmoisture to the places desired. The unit can be readily removed bysimply disengaging the hooks which. v

support it. The nozzle 21 can be withdrawn from the sleeve 16c and theunit is then entirely de tached. It can very easily again be placed inoperating position. The same is easily and inexpensively made andassembled.

It is possible in some places to use the device without the outer casing16a. The air then enters the large end of the casing 40 withoutfirstpassing through the openings in the bottom of the casing 16a. Whencasing 16a is used, the air passing upwardly from the radiator passesthrough the openings in casing 16a and a more uniform movement of theair is secured.

The device has been amply demonstrated in actual practice and found tobe very successful and eificient.

It will, of course,.be understood that various changes may be made inthe form, details, arrangement and proportions of the parts, withoutdeparting from the scope of applicants invention, which generallystated, consists in a device capable of carrying out the objects aboveset forth, in the parts andcombinations of parts disclosed and definedin the appended claims.
